Determine the energy required to crush the material from 25 mm to 3.5 mm. Assuming a Ritttingers law b Kicks law c Bond law 2 A material is crushed in a blake jaw crusher such that the average size of particle is reduced from 50 mm to 10mm with the consumption of energy 13.0KWkgs.What could be the consumption of energy needed to crush ...
Jun 02, 2017 Kicks Law states that the energy is proportional to the size reduction ratio. The equation for Kicks Law can be written as ... much like a jaw crusher. Grinding Mills and Pulverizers. ... Ball mills typically use water or other liquid and additives to help reduce friction and provide cooling during the grinding process. The feed enters ...
Equation 11.2 is a statement of Kicks Law. It implies that the specific energy required to crush a material, for example from 10 cm down to 5 cm, is the same as the energy required to crush the same material from 5 mm to 2.5 mm. ... In a jaw crusher, the material is fed in between two heavy jaws, one fixed and the other reciprocating, so as ...
2. Kicks law applies Question A material is crushed using a Dodge jaw crusher. The particles are reduced from 50 mm to 10 mm with an energy consumption of 13 kmkgs. What would energy consumption be needed to crush the same material from surface-volume diameter equal to 75 mm to 25 mm assuming 1. Rittingers law applies 2. Kicks law applies
Transcribed image text A material is crushed in a jaw crusher in which a 15tonshr feed of average size of 50 mm is reduced to 10 mm while consuming 225 kW of power. By using Kicks as well as Rittingers law, compute the power consumption to crush the same material of 75 mm average size to 15 mm.

Jaw crushers Gyratory crushers . Jaw crusher Feed is admitted between two jaws, which are open at the top like V One of the jaws is fixed and vertical, while the other is the swinging jaw This jaw reciprocates in a horizontal plane and makes the angle of 20-30 with the fixed jaw
Although jaw crushers are extensively used for a variety of materials, their operational characteristics are not well understood. This lack of understanding makes selection of the proper machine difficult. Hersam 1923 proposed a method for calculating capacities using a Dodge-type jaw crusher.
The power requirements for jaw and gyratory crushers are about the same but in choosing between the two crushers, is the criterion. Taggarts formula The capacities with gape maximum distance between fixed and moveable jaws of 4 inches to 2 feet can be approximated by the .
The power required to crush the limestone was 8 kW. Estimate the power required Kicks law to crush the same limestone having a mean size of 2 mm. Assume all material charged had to be crushed. 4.11. The closed set of an operating jaw crusher was 125 mm. A
c A Blake jaw crusher is used for crushing limestone such that the average size of the particles is reduced from 50mm to 10 mm with energy consumption of 50 W.hrmetric ton. Calculate the energy consumption for crushing the same material from average size of 75mm to 20mm. Use Rittingers law, Kicks law and Bonds law. 07
The ore is to be broken down in a jaw crusher to pass through a 11.5 cm screen. The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 th and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the production rate.

Mar 11, 2016 Rittingers theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter or, as I have more fully expressed it The work done in crushing is proportional to the surface exposed by the operation or, better expressed for this purpose, the work done on a given mass of rock is proportional to the reciprocal of the ...
Mar 11, 2016 Kicks law is The energy required for producing analogous changes of configuration of geometrically similar bodies of equal technological state varies as the volumes
Jul 12, 2017 Kicks Law It state that the work required for crushing a given material is proportional to the logarithm of the ratio between the initial and final diameter.
a Rittingers law. This is given by E KRfc1L2 1L1 Thus 13.0 KRfc 110 150 and KRfc 13.0 504 162.5 kWkg mm Thus the energy
Jun 02, 2017 The equation for Rittingers Law can be written as E K R f c 1L 2 1L 1 Where EEnergy, K R Rittingers Constant, f c crushing strength of the material, L 1
where K K is called Kicks constant and f c is called the crushing strength of the material, we have dEdL K K f c L-1. which, on integration gives E K K f c
Aug 14, 2021 Kicks law applies Question A material is crushed using a Dodge jaw crusher. The particles are reduced from 50 mm to 10 mm with an energy consumption of 13
In fluidization experiment, convective heat transfer is described by 1 Point O Fouriers law Newtons law of cooling O Kicks law None of the above 5. The power
